Hissing and Sutekh Hexen are two of the murkiest, most cacophonous groups operating in the margins of the contemporary metal underground. Now, these hellish projects have come together to release a split LP on The Flenser.

Due out October 6th on digital and vinyl formats, this split is streaming in its entirety today on Noisey who said it “will give you nightmares.” Listen here.

Since 2008 Sutekh Hexen have turned the paradigm of black metal completely on its ear. The group can be described as a dense tapestry of black noise, or a wall of intricate tones deconstructing itself brick by brick. Their rich, unparalleled compositions cultivate further interest with each listen.

Founded in 2014 out of a mutual interest in exploring deranged and punishing sounds, Seattle’s Hissing is often described as “blackened sludge.” This descriptor does little justice describing the harsh, dissonant soundscapes created by this trio. To date they have released two EPs through Disorder Recordings and Southern Lord, and have a full-length forthcoming.
